We're not sure if this falls under stupid cycling, stupid driving, or both. Queensland Police have released video of a man sitting on a bike mounted on the roof of a moving car. Not for long, though, as the driver has the sense to pull over when he realises there's a patrol car behind him.

In a video released to Australia's 9 News, police dashcam footage shows a man on a bike on top of the car, as another attempts to climb out of the passenger window to join him on a second bike.

The passenger climbs back in as the car pulls over, leaving the bike rider on the roof in a solo breakaway.

Queensland police chiefs called it one of the most dangerous road stunts they had ever seen.

"I just shook my head and thought how can collectively three people think so stupid together," Queensland Police Inspector of Road Policing Operations Peter Flanders said.

"They would have landed straight on their head and we would have had another fatality, absolutely have another fatality purely because they thought it was a great idea to ride a push bike on top of a moving car."

The driver was fined AU$600 (£305), banned for six months and put on probation for two years.

The rooftop passenger is not believed to have got the idea from Mark Cavendish, shown above at the 2012 renewal of Jaguar's partnership with Team Sky.
